In order to make it easier to add signing support to web applications, we recommend using a JavaScript library with a unified API that allows different plugins to be used in a similar way (independently of the operating system and the browser).

In Estonia, the term “digital signature” (i.e. digi-signature, digital signing, etc.) refers only to a signature that is legally valid and legally equivalent to a handwritten signature.

In Estonia, the BDOC format and its two subformats are used for digital signatures, which can be recognised by .bdoc and .asice file extensions.

In order to use mobile-ID, you only need your smartphone and mobile-ID PIN codes. Today almost all larger e-services have mobile-ID support, providing the option to log in with an ID-card, and mobile-ID works on a computer, a tablet as well as a mobile phone.

We recommend using an e-seal instead of mass signing with the ID card

Digital signatures given with Lithuanian mobile-ID can be conveniently verified via DIgiDoc4.

All ID card, digital ID and/or mobile-ID holders have an allotted number of free digital signatures every calendar month. The limit affects signing for personal use and only digital signatures executed through ID-software.

Using DigiDoc4, the e-signature confirmation page can be saved and printed. The confirmation page displays data on the signed files and the signers.

Did you know that DigiDoc4 allows you to conveniently and rapidly verify digital signatures given with the Finnish ID-card and sign documents using the Finnish ID-card?

Did you know that DigiDoc4 allows you to validate digital signatures given with the Latvian and Lithuanian ID card as well? And that you can use the Lithuanian and Latvian ID cards for signing?
